这在以前的 Tomcat 服务器 (8.0.5) 中没有发生。有解决办法吗？

注意：在我的previous question（一年前）中，我禁用了 HTTP 监视器以抑制警告。这不是一个解决方案。

_{编辑：我忘了提，但很明显，此警告出现在与 Spring Security 相关的Filters 在 web.xml 中注册之后。}

【问题讨论】：

在 web.xml 中添加 spring 安全过滤器后我遇到了同样的问题，请有人回答！
暂时禁用 IDE 上的 HTTP 监视器作为临时解决方法，除非/直到将来遇到潜在的合法方法/解决方案。
已在 Tomcat 8.0.27.0 上进行了最新测试，除非禁用 HTTP 监视器，否则会重现相同的警告。

【解决方案1】：

在使用 HttpMonitor 进行调试时，这是一个已知的 NB 错误：

https://netbeans.org/bugzilla/show_bug.cgi?id=204775

HttpMonitor 可以工作，但如果请求的某些部分在 spring 之前处理过（如 spring 安全链），它将跳过请求的某些部分

你可以尝试给 Spring Security 过滤器一个非常高的顺序并希望它工作，我对此表示怀疑。
